MATLAB: Fortran mex for Matlab 2018b on Mac, OS 10.14.1 (Mojave)

MATLABmex compiler

I need to run Fortran mex scripts with Matlab 2018b. Intel Studio Parallel Studio XE 2019 does not work, and the 2018 version cannot be installed.

I downloaded the latest version of Intel Parallel Studio XE (2019), and ran "mex -setup – v FORTRAN"

mex -setup -v FORTRAN

Verbose mode is on.

… Looking for compiler 'Intel Fortran Composer XE' …

… Looking for environment variable 'IFORT_COMPILER18' …No.

… Looking for environment variable 'IFORT_COMPILER17' …No.

… Looking for environment variable 'IFORT_COMPILER16' …No.

… Looking for environment variable 'IFORT_COMPILER15' …No.

… Executing command 'which ifort' …No.

Did not find installed compiler 'Intel Fortran Composer XE'.

Error using mex

No supported compiler was found. For options, visit

https://www.mathworks.com/support/compilers.

Then I tried downloading and installing the 2018 realease of Intel Parallel Studio XE, but were refused by the installer with the message

Unsupported OS

Detected operating system is not supported. Supported operating systems for this release are:

macOS* 10.12 (Intel(R) 64), 10.13 (Intel(R) 64)

Best Answer

Gave up the intel fortran route, and managed to get my setup working with gfortran, using the presecriptions in https://www.mathworks.com/matlabcentral/answers/338303-how-to-set-up-mex-with-gfortran-on-mac#answer_285758

Thank you so much!

MATLAB: MEX: fatal error LNK1181: cannot open input file ‘Files\MATLAB\R2016b\extern\lib\win64\microsoft libmx.lib

The trailing slash in the library include path is causing problems with the 'link' command being run at the command line. Remove the trailing slash from the library include path.

>> mex -v arrayProduct.c '-LC:\Foo bar\lib*\*'

becomes

>> mex -v arrayProduct.c '-LC:\Foo bar\lib'

This issue will occur with any mex file path inclusions (-I, -L, etc) which contain a path with spaces and a trailing backslash.

As you've discovered, your particular combination of Intel Fortran and Visual Studio is not supported in 14a ( Details ).

You are on the right track if you want to hack something together. None of this is documented or supported, I can offer a few hints:

Don't meddle with the files in your preferences folder ('prefdir'). Instead, put the XML file you are experimenting with in your current working folder ('pwd'). Give it a name like 'custom.xml'; you can instruct MEX to use this file with 'mex -f custom.xml other arguments'.
You are effectively going to want to update custom.xml file such that it preserves the Intel-specific settings, but swaps in the VS2013 settings. This is often, but not always, a largely mechanical process. The file matlabroot\bin\win64\mexopts\msvcpp2013.xml should give you a strong sense of the edits you'll want to make in custom.xml

Hope this helps.
